Top 5 Effects of the Teacher Shortage And What Schools Can Do About It

For decades, school districts have been sounding the alarm about the burgeoning teacher shortage and for good reason. The national teacher shortage isn’t just a staffing issue; it’s a student equity issue and a glaring representation of systemic flaws. And sadly, classrooms all over the country are impacted by its relentless grasp. From small rural schools to bustling urban campuses, the consequences are real: overburdened teachers, overcrowded classrooms, and learners left without the consistent, high-quality instruction they need to thrive.

But students shouldn't have to wait for systemic change to receive the education they deserve. School districts and leaders can do more than just wait for a miracle – they can put a plan of action together and find certified highly qualified teachers now. By embracing synchronous virtual instruction, districts can overcome staffing gaps with certified teachers who are live, engaged, and ready to deliver meaningful learning experiences in real time.

These are the top five effects of the teacher shortage and the solutions that are helping schools rewrite the narrative.

1. Overcrowded Classrooms

Even though districts can’t fill teaching positions, students still need instruction, which often forces existing teachers to absorb more students which can make instruction and classroom management more difficult to navigate. According to NEA surveys, classrooms with 33–40 students make it nearly impossible for teachers to meet individual learning needs, stretching instructional quality thin and increasing educator burnout. Research consistently shows that smaller class sizes around 15 students can boost achievement by up to three months of extra learning and enhance long-term outcomes, especially in early grades.

Solution: Proximity Learning’s virtual teachers can step in quickly, effectively reducing classroom overcrowding. This blended model echoes research on blended learning, showing how combining digital instruction with in-person facilitators allow educators to better circulate and give students individual attention. By partnering virtual teachers with in-person staff, schools can maintain student engagement and reduce strain on overloaded educators without compromising educational outcomes.

2. Learning Loss in Critical Subjects

STEM courses, foreign languages, and advanced placement classes are often the first to be cut or consolidated due to staffing and budget deficits. Students lose opportunities they need for college readiness and career development. McKinsey & Company research shows that these subjects experienced some of the steepest learning losses during the pandemic, especially for low-income and under-resourced students. Math and science learning setbacks, in particular, are tied to decreased engagement and limited access to high-quality instruction according to the Brookings Institute. 

Solution: Leverage synchronous virtual learning for superior student engagement in every classroom. Studies show that synchronous online environments help maintain a strong sense of community and belonging, which are key drivers of motivation and persistence in difficult subjects like STEM and foreign language learning. Our virtual certified teachers stream lessons live, so students continue receiving rigorous instruction no matter the subject or setting.

3. Burnout and Turnover Among Existing Staff

When teacher shortages persist, the pressure intensifies on the remaining staff as they work longer hours, juggle multiple roles, and face mounting stress. According to an article published on class.com, “Nearly 44 % of K–12 teachers in the U.S. report frequent burnout, with 67 % viewing it as a very serious issue, and over half planning to leave sooner than expected.” Furthermore, studies have linked this chronic overload not only to emotional exhaustion, but to compromised teaching quality, disrupted school culture, and significant declines in student learning as burnout drives turnover and systemic failure.

Solution: Supplemental virtual instruction reduces the burden on in-person staff and allows districts to provide support without overloading existing teams. Hybrid and virtual learning solutions have been shown to alleviate teacher burnout by streamlining administrative tasks, building flexibility, and offering peer and professional development support. By integrating certified virtual instructors, schools can redistribute teaching loads, preserve staff mental health, and promote long-term retention thereby breaking the cycle of overwork, burnout, and turnover. 

4. Inconsistent Student Learning Experiences

Temporary fill-in substitute teachers and long-term vacancies often result in a patchwork of instructional quality. Without a consistent educator, students miss out on strong relational bonds and coherent lesson delivery from a content and pedagogy expert. Research shows that positive teacher-student relationships significantly boost academic achievement, and frequent changes in instructors hinder that growth, especially in environments reliant on substitute staffing. Additionally, high-quality instruction and stable leadership directly influence learning outcomes, meaning that inconsistency disrupts students’ educational development.

Solution: Synchronous virtual teachers provide much-needed continuity. By delivering live, streamed lessons, students interact daily with the same certified instructor, allowing them to build rapport and experience a consistent learning rhythm. Studies highlight that synchronous virtual engagement fosters a strong sense of community and supports real-time interactivity all of which are key factors in student motivation and retention. Moreover, education providers like Proximity Learning demonstrate that seasoned virtual teachers establish meaningful, lasting connections with students, even when onsite staffing is unstable. This consistency not only enhances academic outcomes but also restores trust and cohesion in the classroom environment.

5. Widening Equity Gaps

Teacher shortages hit hardest in underfunded and rural districts areas where recruiting and retaining qualified educators is the most difficult. In fact, rural students in poverty score 22 points lower in math and 18 points lower in reading compared to their wealthier peers, a discrepancy closely tied to lower teacher pay and resource allocation in those communities. Chronic shortages have led to higher turnover in high-poverty and rural schools, undermining instructional quality and limiting course access. This inequity compounds over time because when schools lack certified teachers, especially in specialized subjects like STEM, Special Education, or ESL/LEP(Language Acquisition), the learning gap widens and students lose foundational opportunities and support.

Solution: Virtual learning helps level the playing field across the nation no matter what district serves the student. By streaming synchronous instruction from certified virtual teachers, every student regardless of their zip code gains access to high-quality courses. Virtual platforms can expand rural and underfunded districts through expanded course catalog options and additional faculty support. This positively impacts student outcomes by enabling access to advanced subjects previously unavailable. They also serve as professional support systems: virtual teachers contribute to communities of practice and ongoing training, addressing isolation and equity barriers. When delivered reliably, real-time virtual instruction ensures that all students receive consistent, certified teaching thereby reducing inequities tied to geography and funding.

A Smarter, Stronger Solution

The teacher shortage is a complex, nationwide challenge, but it is not without solutions. While school districts across the country continue to grapple with unfilled vacancies and high turnover, instructional quality doesn’t have to be sacrificed. Our teacher shortage solutions bring certified, engaging educators into classrooms through the power of synchronous virtual instruction. These are not pre-recorded lessons or one-size-fits-all modules. Our teachers are live, present, and fully integrated into the school community. They deliver rigorous, relationship-driven instruction that meets the unique needs of every learner.

The reality is that the teacher shortage isn’t going away overnight. But school and district leaders don’t have to sit on the sidelines waiting for the tides to turn. They can be the change-makers. By embracing flexible and modern staffing solutions like live-streamed instruction, districts can ensure continuity, expand course offerings, and alleviate the pressure on overworked in-person staff. More than a stopgap, virtual instruction offers a sustainable path forward. It bridges equity gaps, reinforces consistency, and gives every student in every zip code access to certified teachers and an engaging curriculum.
